Modular optical computer chip allows stackable swappable functions
June 20, 2022Engineers at MIT have developed a modular computer chip with components that can communicate using flashes of light. This could allow for electronics that can easily be upgraded with new sensors or processors, rather than replacing the whole chip. -
New heat spreading tech delivers 740% increase in circuit power density
May 22, 2022A team from the University of Illinois and UC Berkeley has demonstrated a new cooling method that sucks heat out of electronics so efficiently that it allows designers to run 7.4 times more power through a given volume than conventional heat sinks. -
Isotope-pure silicon nanowires could make computer chips much cooler
May 17, 2022Heat is a major hurdle for electronic devices. Scientists have now found that nanowires made of a certain isotope of silicon can conduct heat 150 percent better than regular silicon, potentially leading to drastically cooler computer chips. -
Fastest-ever logic gates could make computers a million times faster
May 11, 2022Researchers have now developed the fastest logic gates ever created, by zapping graphene and gold with laser pulses. The new logic gates are a million times faster than those in existing computers, demonstrating the viability of “lightwave electronics.” -
One-way superconducting diode has massive implications for electronics
April 28, 2022A TU Delft team has demonstrated a one-way superconductor that gives zero resistance in one direction, but blocks current completely in the other. The discovery, long thought impossible, heralds a 400x leap in computing speed and huge energy savings. -
Two-inch diamond wafers could store a billion Blu-Ray's worth of data
April 27, 2022Researchers in Japan have developed a new method for making 2-in wafers of diamond that could be used for quantum memory. The ultra-high purity of the diamond allows it to store a staggering amount of data – the equivalent of a billion Blu-Ray discs. -
Ultra-thin speakers roll out like wallpaper for sound-blasting surfaces
April 26, 2022Engineers at MIT have developed an ultra-thin speaker that could be used to make entire surfaces produce sound. The unique design should be energy efficient and easy to produce at scale, the team says. -
E Ink launches faster, full color Gallery 3 ePaper tech for e-readers
April 25, 2022Last month, E Ink launched a new version of its color ePaper for digital signage called Gallery Plus. Now the company is back with a version destined for e-readers that boasts fast update times, high resolution and pen input support. -
World-first quantum dot LED lights made from discarded rice husks
April 12, 2022Scientists at Japan's Hiroshima University have demonstrated a greener path forward in quantum dot manufacturing, by using discarded rice husks to produce the world's first silicon quantum dot LED light. -
E Ink's latest color ePaper technology supports displays up to 13.3 inches
April 08, 2022Around a year ago, we got to gawp at the latest color electronic paper display technology from E Ink when we reviewed the excellent PocketBook InkPad Color e-reader. Now E Ink has launched a new generation that gives the color performance a boost. -
Scientists calculate absolute quantum speed limit for electronics
March 27, 2022It may seem like electronics will always get faster, but at some point the laws of physics intervene. Scientists have now calculated the absolute speed limit – the point at which quantum mechanics prevents microchips from getting any faster. -
Latest E Ink display tech boosts color and contrast
March 25, 2022Back in 2014, we saw some of the first examples of color E Ink display technology. The first full color gamut support came a couple of years later, and now the color gamut and contrast has been bumped up again for E Ink Gallery Plus. -
Disney's "Holobricks" could stack up for larger holograms
March 17, 2022Scientists at Cambridge and Disney Research may be a step closer to making holograms less disappointing, creating new “holobricks” that can stack and tile together to produce large 3D images that can be viewed from multiple angles. -
Tiny dandelion-inspired sensors can be dispersed by the wind
March 16, 2022Imagining a future where hundreds of sensors are placed around forests or farms for large-scale monitoring of the environment, scientists have developed platforms light enough to disperse like dandelion seeds in the breeze when dropped from a drone. -
Cylindrical wireless charger juices up devices placed all around it
March 04, 2022Ordinarily, wireless chargers emit an electromagnetic field in just one direction, limiting the number of devices they can charge at once. A new charger, however, produces a donut-shaped field, for the simultaneous charging of multiple gadgets.
